To all whom t'my concern:

Be it known that i, RAYMOND S'PARsoNs,

"ro housing the terminals Otarmored. conductors used in installing electric wires for lighting and other purposesi The object of the invention is to provide an Outlet-box having aA plurality of radial wirer receivingjtubes or bushings formed integral therewith,'thus dis ensing with the employment of detachab e couplings and similar fastening devices for retaining `the wires or conductors within the box. 2o VA further object is to tornil the tubes or bushings with annular shoulders adapted to engage the'adjacent ends of the flexible armor, thereby to limitethemovement of .the same.

A further Objectis toi provide means for clamping' the conductorsor wires within the tubesfand, further', topro'yide, the inner ends of the tubes with curved orrounded terminals, so as to'prevent injuring the conductors when 3o the latter are threaded 'through said tubes.

A still further object of the' invention is to generally improve this class of devices so as to increase their utility, durability, and eiciency, as wellas to reduce the cost of manu- 3 5 facture.

' With these and other objects in view the invention. consists in the construction and novel combination and arrangement Oi' parts hereinafter -ully described, and illustrated in 4o the yaccompanying drawings', it being understood that various changes in form, proportions, and minor details Oi construction may be resorted to within the scope of the appended claims.

In the accompanying drawings, forming a art of this speciiication, Figure 1 is a iongitudinal sectional view of an outlet or june ture box constructed in laccordance with my invention, showing the same in position 5o on awall or partition. Fig. 2 is a iront elevation of the saine detached. I

Similar numerals of reference indicate corresponding parts in all of the iigures of the drawings.

The improved outlet-box is-principally designed for use in installing concealed wires or conductors for electric lights in houses and other buildings, and by it of illustration is shown in position on the w all or partition of a building ofthe ordinary construction, in which .5 designates one ol the vertical studs or beams, 6 the l'atlis, and 7 the plaster.

The device consists oi ametallic casing or shown, and having one end thereof open and its side walls provided with` a plurality ci radiatingopenin l's or recesses 9 for the recep tionof thecon uctors.

member or bushing 10, having alongitudinal shoulder 12 arranged at the inner end of each tubular member and adapted to',l bear against the end of the adjacent flexible armor, thereby The inner ends of the tubes or members 1() as to prevent abrading or. otherwise injur-t when the latter are l.threaded throu members 1() for connection with the eblectric lights'.

The members are each provided with a iiat surface 14, and threaded through the walls lof said members at'the {iattened porn tions 14 thereof are suitable clamping mem bers, preferably in the form of screws 15, which bear against the vexterior walls of the flexible armor when the latter is positioned the same.

The several members or tubes 10 are con nected by a supporting member 16, having one end thereof thrcaded, as indicated at 17 for engagement with the corresponding threads of an electric-light fixture of the usual construction, whiLe the o posite end thereof is provided with a plurality of radilaterally at 19 for engagementwith the fiattened portions 14 oi the members 10, there being screws or similar fastening devices 20 threaded through the perforations in the arms 19 and the adjacent walls of the 1nemposition on the box or casing.

The casing 8 is preferably retained in posif tion du the stud 5 by means of screws or housing 8, preferably circular in ferm, as4

to limit the inward movementfot thesame. j

are curved or rounded, as indicated at 16, so

ating arms 18, the free ends of which are bent bers 10 for securing the pipe or support 16 in Dispose entirely withinthe casing 8 at' I each wire-receiving opening 9 and preferably formed integral with said casing is a tubular i bore 1 1 formed therein for the reception of the i electric conductor, there being an annularv ing the adjacent terminals of the lconductors 0h the within the tubes or members 10,v and thus serve to prevent accidental displacement of IOO similar fastening devices 2l, which pass through suitable openings 22, formed in one wallof the casing 8, and are screwed or other- Wise embedded. in the stud 5, as shown.

In using the device the covered eomluctors are inserted through the openings 9 Iand seated in the tubes or members 10 with the ad jacent end of the flexible armor bearing against the shoulders 12 and with the terminals of the conductors or Wires passed under the support and thence extended laterally between the arms 1S for connection with the electric-light xture. When only one of the openings 9 are used, the adjacent openings may be 'ptugged by inserting suitable pieces of metal eut to fit the same.

`Wlrle the outlet-box is principally designed for vuse when wiring inished houses, it is obvious that the same may be installed in a house or other building at the time the saine is erected.

Attention is called to the fact that the intermediate portions oi the arms are curved or bowed laterally, so as to allow ample space between the arms and the bottom of the box to iermit the passage of th( wires.

it will of course be understood that the usual canopy or ornamental casing may be employed to cover the open end of thev housing S, so as to give the same a neat attractive appearanee, and that the outlet-box maybe positioned in the wall, ceiling, or other portion of the building.

l ltr-,fhg` thus described th(` is claimed is-m fl. An outlet-box including' a easinghaving an opening formed therein, a nire-receivin member disposed entirely within the easing at said opening and provided with a stopsln,-ulder, and means piercing the n'allsofsaid iemher and engaging the wire for clamping Iie latter within said. member.

jin outh-:t-box including a easing having an opening formed therein, a tubular Wirereeeiving member disposed entirely Within the casing at said opening, and having its inner end curved or rounded and ilsinterior Walis provided with a. stop-shoulder, and means for clamiiing the uire within the tubularinember. l

3. An outlet-box including a easing having an opening formed in the waits thereof, a

invention, what' i l l l l i l, f f l 1 l l l tubular wire-receiving melnber disposed at said opening, a supporting ineniber rigidly secured to said wire-receiving member, and means carried b y the Wire-receiving member and adapted to'engage the wire for preventing accidental displacement of the same.

4. An outlet-box including a casing provided with a plurality of openings, tubular ire-receiving members formed integral with the casing and extending inwardly from the lalter at said openings, and means piercing the walls of the members and engaging the Wires for locking the same against accidental displacement.

5. An outlet-box including a casing having its side Walls provided -with a plurality of openings, tubular Wire-reeeivin5.1 members disposed at said openings and each having one terminal thereof curved or rounded and its interior Walls provided with a stop-shoulder, a supporting member having radiating arms for attachment to the tubular members, and means piercing the tubular members an d engaging the wires for locking the same within said members.

6. An outlet-box including a casing having one end thereof open and its side walls provided with a plurality of openings, tubular Wire-receiving members disposed at said openings and-eaeli having one end thereof curved or roundtl l and its interior walls provided with an annular stop-shoulder, there being a flattened portion formed on each member, a supporting` nieinher having onel end thereof threaded and its opposite end provided with radiating arms having laterallyperforated extensions bearing against the flattened portions of the tubular members, fastening devices passing through the perforations in the extensions and engaging the tubular members, and clam )ing-screws threaded in the Walls of the tubular members and adapted to engage the wires for locking said wires in engagement with the tubular members. l ln. testimony that I claim the foregoing my own I have hereto aHiXed my signature in the presence of two wit nesses.
